Your indie game can look like a AAA masterpiece without blowing your entire budget!
With the right free 3D game assets, you can create stunning visuals, immersive environments, and jaw-dropping effects.
In our latest tutorial video, we break down everything you need to know about assets, from file formats to shader tricks, and where to get the best models, materials, and skyboxes for free.
Here’s a quick breakdown of what the video covers—plus why you should watch the full thing if you’re serious about leveling up your game’s visuals.
What Types of Assets Makes a Game Look AAA?
It’s not just one thing—it’s everything working together:
• 3D models: the characters, props, and vehicles in your world
• Textures & materials: these define how things feel visually, from gritty sand to shiny metal
• Skyboxes: 360° backgrounds that set the mood and lighting
• Shaders: code-powered visual effects that give your game that extra wow
Assets File Formats Made Easy (GLB, glTF, FBX, OBJ)
If you want a smooth workflow on Rosebud, stick to GLB or glTF.
These formats usually include everything—textures, animations, lighting—bundled in one tidy package.
While FBX and OBJ still work (and are super common), they often need extra setup, which can lead to missing textures or broken models.
Where to Get the Best Free 3D Game Assets
Here is a killer list of free sites you can pull from right now:
• Kenney.nl: Legendary for clean, game-ready assets (GLB/glTF supported)
• Quaternius: Huge variety, including kits and modular packs
• PolyHaven & AmbientCG: Amazing for skyboxes, textures, and HDRIs
• ShaderToy: Browse crowd-sourced shaders and copy effects into your own games
• Mixamo: Upload a static model and auto-generate animations
• RTFKT Market: Tons of detailed models, many under Creative Commons
Most of these assets come with open licensing (CC0 or CC BY), which means you’re safe to remix and publish without headaches.
